Linthra is an open-source, offline-first music player for Android. Play the music stored on your device without an internet connection or a Linthra account. Optionally connect to your own Jellyfin, Navidrome / Subsonic, or Plex server to browse and stream your personal music library. Linthra is an independent community client and is not affiliated with Jellyfin, Navidrome, Subsonic, or Plex. What Linthra offers: * Local music playback: select a music folder or use the optional "All music on this device" library, with support for common audio formats including MP3 and FLAC. * Browse songs, albums, and artists; search your library and use playlists, favourites, queue / Up Next, shuffle, and repeat. * Connect to self-hosted music servers when you want to stream your own collection, including over HTTPS. * Download selected tracks for offline listening with a configurable cache. * Background playback with notification, lock-screen, Bluetooth, headset, and Android Auto media controls. * Album artwork, synced lyrics where available, and optional Chromecast playback to compatible devices. Privacy first: * No ads, tracking, analytics, or telemetry SDKs. * No Linthra cloud account and no forced synchronization. * Your local files stay on your device. Network connections are optional and used for the self-hosted sources and features you choose. * Licensed under the GNU Affero General Public License v3.0 or later (AGPL-3.0-or-later), so anyone can inspect, build, and contribute to the code. Linthra is actively developed, and some features depend on your Android device or the capabilities of your connected music server.
